VACUUM-CLEANER.

To all whom it may concern:

Be itknown that I, DANIEL B. Rnrroonn, a citizen of the United States,residing at Berkeley, in the county of Alameda and State of California,have invented certain new and useful Improvements in Vacuum- Cleaners,of which the following is a specification.

The present invention relates to electrically operated manually portablevacuum cleaners. The objects of the invention are to provide hollow aircarrying handles for such cleaners, to combine electrical conductors andconnections through the walls of said handles, and to improve the meansof connecting said handles to the vacuum producing means and dustcollecting systems now in use.

To these ends, the invention consists of the construction, arrangementand combinations of parts as herein described and illustrated in theaccompanying drawings in which,

Figure 1 is a side view of a cleaner embodying the essential features ofmy invention. Fig. 2 is a partial front view. Fig. 3 is an enlargeddetail cross section on line m--a2 of Fig. 1. Fig. 4 shows extensiontube and cleaning connections slidable within the main tube of thedevice. Fig. 5 shows detail view of air control. Fig. 6 shows detail ofdeflector used in air control.

Fig. 7 shows a substitute form of the cleaner adapted to blow the dustcollected through the hollow handle. Fig. 8 is an underside view of thefloor tool and its con nections, in the substitute form. Fig. 9 shows alink used to connect floor tool shown in Fig. 8. Fig. 10 is a rear viewof the roller supports used in the substitute form. Fig. 11 shows methodof connecting the substitute form of the cleaner to base board hose ipeand electrical connections.

Re erring to the several figures, the main tube 1 connects to the commonform of electrically operated cleaner having a motor 2 driving a fanwithin the fan case 3. The tube 1 may serve either as suction or blowingpipe, and when used for suction it may have a flexible tube 4 and ahinge ring member 5 for connection purposes. The ring 5 is hinged to alug 6 by means of a bolt and nut 7. The tube communicates with the portof the fan case and tool or nozzle 10 through the suction chamber 8 andis held in position by means of the clamp ring!) Specification ofLetters Patent.

fitting to the nipple 9'. The nozzle 10 may have roller supports 11, 11.The rollers 12, 12 support the main weight of the whole device.Similarly the flexible tube 15 is slid within the tube 15 through thenipple 17 and extending to 17 or beyond, so that the three parts of thehandle are all telescoped together, when not in use. The main tube 1 mayalso be connected to the exhaust 13 or 13 when it is desired to use itas a blowing pipe. A. clamp 14 is designed to contract the upper end ofthe main tube 1 and the extension tube 15 having a plain lower end 16and a tool attachment nipple 17 at its upper end is slidable within themain tube, but may be secured from sliding by tightening the clamp 14. Aflexible tube 15' operably connecting with a cleaning tool 15"illustrates a use of this tube 15, which may be slid within until itslower end reaches the point 16' when shipping or carrying the deviceabout. A control valve or deflector 18 swinging on the shaft 19 andturnable by the wing knob 19' is operably connected within the suctionchamber 8.

The walls of the main tube 1 are of electrical insulation material. Fromany source 20 an electrical cord 21 carries current to the connector 21connecting with the strips of copper or other good conducting metal,embedded or secured in the walls of the tube, being thus insulated fromeach other and from without and within the tube 1. The wires of theconduction cord are designed to suitably connect to the terminals 24 and25 which are in turn suitably soldered or connected to the strips 22 and23 in the wall of the tube 1. These strips or flat wires are preferablywrapped in between the layers of adhesive paper or fiber during themaking of the tube and are bared by rasping off or cutting whensoldering to them is required.

In the substitute form shown in Fig. 7 a conduit 3' closable with a cap3" and fitted with a flexible hose 4' takes the place of suction chamber8 in the other form, and the nipple 3* connects to the tube 1 by meansof a ring clamp 3" and braces 12 having keepers 12" connect the rollersupport 2 with the floor tool 10. In this form the fan case 3 is amodified form of the case 3 by having the exhaust 13 extended in lengthand brought to substantially a perpendicular to the plane of the fancase and threaded,

so as to be adapted to securing the handle 1.

In this form also the section of flexible hose 4' serves as a flexiblejoint, operably connecting the floor tool 10 to the suction chamber 8leading into the port of the fan case. This joint is in close proximityto the axes of the roller supports 12, 12 whereby free swinging of thehandle 1 is permitted Without strain on said flexible hose.

In operation of the form shown in Fig. 1 the air current or suction isthrough the floor tool or handle according as the deflector is set tothe full or dotted line position in Fig. 5. When it is desired todeliver dust through the handle, instead of using same for suction, thehandle 1 is to be connected either directly, or indirectly by means ofthe short hose, to the nipple 13 or 13 and the, outer end of the handlecommunicates with any hose pipe leading out of the room as suggested inFig. 11.

Having thus described the invention it is evident that many variationsof detail may be adopted without departing from the intent of the claimswhich are:

1. A vacuum cleaner comprising, portable electric motor driven vacuumproducing means, a suction tool arranged to cotiperate therewith forgathering dust, a main tube having walls of insulating material,electric conductors leading to the motor driven matinee means, embeddedin the said walls, the said main tube being operably connected andadapted to serve as a handle to the device, to carry dust laden air. andalso to serve as an insulator of the said conductors.

2. In a vacuum cleaner, vacuum producing means, a suction tool, aconduit operably connecting said suction tool to the vacuum producingmeans, roller supports carrying said vacuum producing means, a portionof the conduit aforesaid being a flexible hose in the vicinity of theaxes of said roller supports; together with a handle secured to, andcarrying the said parts.

3. In combination, portable electric driven vacuum producing means, asuction tool, a conduit operably connecting said suction tool to thevacuum producing means and adapted to lead air thereinto; and a rigidtubular conduit, suitable as a handle, operably connected to said vacuumproducing means and arranged to simultaneously lead air therefrom.

In testimony whereof I aflix my signature in presence of two witnesses.
